Description:

This node group takes roughness into account when calculating Fresnel.

The group also has enhancements for roughness and color.

Grazing Reflectivity: This produces realistic reflections at grazing angles. The Grazing Reflectivity parameter controls the strength. The GR Falloff parameter extends the reflections.

Color Correction: This addresses an issue that causes color to appear too dark at grazing angles.

The group is compatible with 2.79 and 2.8.

    I have also created a Grazing Reflectivity group for the Principled shader. https://www.blendswap.com/blend/23960

    Just to clarify, does a higher falloff extend or shorten the reflections?

    Higher values extend the reflections.
